WHITEMARSH — A Lafayette Hill doctor has been charged with illegally doling out tens of thousands of prescription pills to patients he knew were drug-dependent, without even a physical examination.

According to a criminal complaint obtained by The Times Herald, Dr. Michael B. Rosen, of Lafayette Hill Family Medicine at 590 Germantown Pike, was arrested more than two weeks ago and charged with narcotics possession and related offenses. The report, which Whitemarsh police unsealed Wednesday, says the patients referred to Rosen as “Dr. Feel Good.”

“Dr. Rosen continued to treat and write narcotic prescriptions to these three patients after knowing they were drug-dependent on the very drugs he was prescribing,” the criminal complaint states.

On Nov. 11, 2011, police reportedly interviewed one of Rosen’s patients, who told them he suffered no injuries or had bodily pain, but had been a recipient of Rosen’s prescriptions for nine months. Ten of those prescriptions were allegedly postdated, which police said was “very suspicious.”

It was not long before police found at least two of Rosen’s other patients to also have “an exuberant amount of narcotics prescribed by Dr. Rosen,” according to the criminal complaint.

Another man, a patient of Dr. Rosen’s for two years, told police that he lied to Rosen about back pain to get a prescription for Percocet.

“Dr. Rosen did not perform any examination or even look at his back, he just gave him the prescription for Percocet,” the report reads. “(The patient) continued to say that Dr. Rosen was aware that (the patient) was a drug abuser and was previously on Suboxone and was in drug rehabs for his abuse. He stated he would continue to go to Dr. Rosen and tell Dr. Rosen what he wanted as far as prescriptions went.”

On April 25, 2012, Whitemarsh police detectives executed a search warrant for medical records of patients who had a large amount of pain narcotics prescribed to them.

Findings from the search warrant resulted in the discovery of a third patient who went to see Rosen in February 2009. The patient reportedly told the doctor he was not on any medications, he worked out regularly but suffered from anxiety. Rosen reportedly prescribed Xanax and another drug without consulting any other prior physicians.

“A mother of one of the victims came to police seeking help,” said Whitemarsh Police Chief Michael Beaty. “We met with her and realized there was a problem that went way above what we thought. We conducted a thorough and complete investigation for over a year to put this thing together.”

“We will continue to gather information and evidence, but to comment further at this time would just be improper,” he said.

According to the criminal complaint, the three patients returned to Rosen for prescriptions over the course of two years, some with complaints ranging from hypertension to chronic back pain to respiratory infections. One patient received a total of 10,000 “controlled substances” over a nine-month period, according to the complaint.

In all three reported cases, investigators found Rosen failed to administer a basic physical examination, check with patients’ prior physicians, obtain prior medical records or maintain accurate or up-to-date medical documentation of treatment and prescriptions.

Rosen was arraigned before District Judge Deborah Lukens on April 4 and released on $10,000 bail. A preliminary hearing is scheduled for May 21.
